Now that Valentine's Day is over, it's time to celebrate the next national holiday -- Paris Hilton's 33rd birthday. The heiress and former reality star is notorious for throwing multiple bashes on her birthday, and on Feb. 15 she didn't disappoint with a wild party at Greystone Manor in West Hollywood.

"This was one of the couture gowns [from the runway show], and I said, 'I have to wear that for my birthday it's like the perfect Barbie princess dress,'" Hilton revealed to Us Weekly.

The former Simple Life star officially turns 33 on Feb. 17, but has plans for "about a month" of celebrating. She had a party at the Marquee in New York prior to her Hollywood bash, and traveled to Miami this weekend to perform before heading to Brazil and Las Vegas for more festivities and rounding it out with a soiree at her Los Angeles home.

Hilton, who is currently dating Spanish model River Viiperi, said her beau has a surprise planned for her this President's Day.

"I like things that come from the heart," she revealed. "[River] made me a really beautiful sculpture for Valentine's Day and a love letter that was so sweet so I love things like that. He's very romantic."

After releasing her new song "Good Time" last fall, Hilton has plans to finish recording her album in Miami. Her dream collaboration? Nicki Minaj.

"I think she has such amazing style," Hilton revealed. "She's so cool and has a fun personality and I love her music."

But when it comes to reality TV, Nicole Richie's former bestie isn't quite as eager to dive back in.

"I get offered shows every single day, and I turn everything down," she admitted. "I'm so busy with my career and traveling every day that I don't have time for that right now. Unless something's very interesting than maybe but for now it's not a priority."?
